Narrow Web and Label Corona Surface Treatment Equipment

  • Corona treatment of narrow web & label
  • Narrow web & label printer

The purpose of corona surface treatment of polymer based materials is to increase surface wettability through electrical discharge. The low surface energy of polymer based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Surface treatment with corona results in good wetting of the material over the surface of the substrate and so improves adhesion.

Our narrow web and label corona treating systems can be supplied to treat either one or both sides of the web and can accommodate widths from 10 to 500mm running at production speeds of up to 150m/min. The narrow web corona treater is designed for the pre-treatment of conductive and non-conductive narrow webs.

•    Compact design & construction.
•    Easily fitted to new or existing production lines or presses.
•    Ceramic electrode elements for uniform surface treatment.
•    Good accessibility for initial web thread-up.
